Copy of the original phone of Alexander Graham Bell at the Musée des Arts et Métiers in Paris Telecommunication is the assisted transmission of signals over a distance for the purpose of communication. ...

The duty cycle D is defined as the ratio between the pulse duration (τ) and the period (T) of a rectangular waveform

Duty cycle is the proportion of time during which a component, device, or system is operated. Suppose a disk drive operates for 1 second, and is shut off for 99 seconds, then is run for 1 second again, and so on. The drive runs for one out of 100 seconds, or 1/100 of the time, and its duty cycle is therefore 1/100, or 1 percent.

In a periodic phenomenon, the ratio of the duration of the phenomenon in a given period to the period.

duty cycle

where

D is the so-called duty cycle;

τ is the duration that the function is non-zero;

Τ is the period of the function.

For example, in an ideal pulse train (one having rectangular pulses), the duty cycle is the pulse duration divided by the pulse period. For a pulse train in which the pulse duration is 1 μs and the pulse period is 4 μs, the duty cycle is 0.25. The duty cycle of a square wave is 0.5, or 50%. In signal processing and telecommunication, the term pulse duration has the following meanings: Pulse duration using 50% peak amplitude. ... A square wave is a kind of basic waveform. ...

For another example, the duty cycle for a piece of electrical equipment (such as an electric motor) is the period for which it may be operated without deleterious effects, such as from overheating.

In a continuously variable slope delta (CVSD) modulation converter, the mean proportion of binary "1" digits at the converter output in which each "1" indicates a run of a specified number of consecutive bits of the same polarity in the digital output signal. Continuously variable slope delta modulation (CVSD or CVSDM) is a voice coding method. ... The binary numeral system, or base-2 number system, is a numeral system that represents numeric values using two symbols, usually 0 and 1. ... Output is the term denoting either an exit or changes which exits a system and which activate/modify a process. ... For other senses of this word, see sequence (disambiguation). ...

Some music synthesizers vary the duty cycle of their audio-frequency oscillators to obtain a subtle effect on the tone colors. This technique is known as Pulse-width modulation (PWM.) The term synthesiser is also used to mean frequency synthesiser, an electronic system found in communications. ... In music, timbre is the quality of a musical note which distinguishes different types of musical instrument. ... An example of PWM: the supply voltage (blue) modulated as a series of pulses results in a sine-like flux density waveform (red) in a magnetic circuit of electromagnetic actuator. ...
